WATER-ELEVATOR.

SPECIFICATION forming part Of Letters Patent NO. 337,251, dated March 2, 1886.

' Application tiled December 14, 1885. Serial No. 185,641. (No model.)

To all whom it may concern:

Be it known that I, JoHNsoN O. DAVIS, of Athens, in the county of Clarke and State of Georgia, have invented a new and useful Improvement in Water-Elevators, of which the following is a description.

My invention is-an improvement in waterelevators, and particularly in that class of such inventions employing a pivoted waterspout and trip devices connected therewith and arranged to be engaged and actuated by the water-bucket.

The invention consists in the peculiar features of the trip mechanism constructed and combined, as will be described, and in other improvements hereinafter described.

In the drawings, Figurel is a side elevation, the casing and a portion of the well being shown in section. Fig. 2 is a partial vertical section on line 00 m, Fig. 1; and Fig. 3 is a detail top plan view illustrating the detent mechanlsm.

The frame or casing A may be of ordinary construction and is provided with bearings for the shaft B. This shaft is provided with a" rope drum, 0, and with ratchet -disks D E, having their teeth facing toward opposite sides of the frame. Pawls d e are pivoted at their outer ends at the opposite sides of the frame, and have their inner ends arranged to engage, respectively, the disks D and E. A link, F, joins these pawls and is pivotally connected to each. By this link one pawl is held clear of, and the other in engagement with, their respective ratchets.

It is usual to employ two buckets-one on each end of the rope, as shown; but as a single bucket would operate, I will describe the invention as used in connection with a single bucket.

The trough G is pivoted at g to the framing, and has its forward or discharge end movable through an opening, a, as will be understood from Fig. 1. To thistrough I pivot the lower end of the arms h of bail H. These arms h are spread laterally apart toward their upper ends, where they are connected by a suitable cross bar. By this lateral spreading of the arms a sufficient space is provided between their upper ends for the upper end of the bucket, so the latter will properly engage the cross-bar of the bail. The upper end of the bail is connected with the frame or casing by a flexible connection, I, preferably a chain, as shown. This chain, when taut, holds the bail in position to be engaged by thebucket, as shown at the left in Fig. 1, and yet permits the upper end of the bail which is on the side of the rope farthest from the framing to adjust toward the side of the framing as the bucket rises and draws the trough up to the position shown at the right in Fig. 1. I prefer to provide the trough with a projection, j, by which to engage a valve in the bottom of the bucket J; but manifestly,where so desired, the valve may have a depending stem by which to engage the trough and be tripped.

It is preferred to form the bucket with a depending portion, K, surrounding its dischargeopening, the bottom on each side of this portion K forming a rest-flange, 7a, which rests on the rim and holds the discharge-opening clear of the bottom of the spout, so the water may freely pass out of the bucket.

A bracket, L, secured to the framing, performs the double function of a stop for the upper end of the bail, to limit the movement thereof and prevent its being adjusted toward the framing beyond the center of gravity of the bail, and also as a means to steady the bucket as the water is being discharged.

By preference I weight the outer or nose end of the trough at M, in order that when such trough has been tilted outward off its balance by the bucket the weight B will throw the inner end of the spout up with force to insure the opening of the valve in the bucket by the projection provided for such purpose.

Manifestly the trough might be turned up into the position shown at the right in Fig. 1 by hand; but to render the working automatic, and for the further purpose of equalizing the weights, it is preferred to weight the crown or cross-bar of the bail at N. This weight N is usually formed of two plates, at n, bolted together on the cross bar or rod and grooved to provide between them a way for said rod. The weight is provided with a notch, 11, in its inner side, to permit the passage of the rope.

The weights M and N are, for instance, re spectively five and five and one-half pounds. In operation it will be seen, instead of having to lift eight or ten pounds, in addition to the weight of the bucket and contents, there will to, of a bail having its lower end pivoted to the inner portion of the spout, and a flexible connection extended between the upper portion of the bail and the framing,whereby said bail will be held normally in position for engagement by the bucket and may be swung on its pivotal connection with the spout, substantially as set forth.

3. The combination of the framing, the pivoted water-spout, the trip bail pivoted at its lower end to the spout, a flexible connection extended between the upper end of said trip and the framing, and a stop whereby to limit the forward movement of the upper end of said trip-bail, substantially as set forth.
